title: Cost effectiveness of multi detector CT angiography of the coronary arteries for the diagnosis of suspected non-ST elevation acute coronary syndrome (NSTE-ACS) in the emergency department. Mathematical analysis with a decision model.
abstract: The purpose of our study is to model cost-effectiveness of MDCTA for the diagnosis of NSTE-ACS with initially negative enzymes, in the emergency department. In Belgium, the use of multi-detector computed tomography (MDCTA) is probably cost-effective in the diagnosis of NSTE-ACS in the acute setting A decision tree model was developed and a mathematical study was performed that included two hypothetical strategies: MDCTA and admission with classic clinical follow-up and treatment. Cost-effectiveness for the Belgian situation was simulated with sensitivity analysis using known values for diagnostic performance and known costs for the different strategies or components of strategies.
